A process for purifying semi-conducting single-walled carbon nanotubes (sc-SWCNTs) provides electronic grade materials with sc-SWCNT purity in excess of 99.99%. An initial dispersion containing sc-SWCNTs and metallic SWCNTs (m-SWCNTs) dispersed in a non-polar organic liquid medium is exposed to a fiber-like adsorption medium. The fiber-like adsorption medium preferentially adsorbs m-SWCNTs over sc-SWCNTs from the initial dispersion. A purified dispersion is collected after exposure of the initial dispersion to the fiber-like adsorption medium. In the purified dispersion a weight ratio of m-SWCNTs to sc-SWCNTs is smaller than a weight ratio of m-SWCNTs to sc-SWCNTs in the initial dispersion.
